This invention relates to machines in which a sheet of textile material is advanced while being treated, as with a sizing substance, and it consists in certain improvements in these machines whereby the sheet may be made to travel through the machine forward at high speed or low speed or reversely at low speed; whereby there may be positively maintained a predetermined and definite degree of tension on the sheet between the quetch (or equivalent means to apply the size) and the drying means; and whereby a predetermined degree'of pressure on the sheet by the rolls of the quetch may be precisely realized.

Figs. 11 and 12 are diagrams of different forms of the electrical part of the mechanism.

What will first be described has been heretofore been disclosed by me, to wit: In the frame I are journaled the drying drums 2, intergeared at 20. and suitably heated, and a suitable take-up 3. What I term the driven element, a shaft 4, is suitably connected with the nearest drum by a longitudinal shaft 5 (intergeared with such element and drum) and with the take-up by gearing 6, whereby said element drives the drums and take-up. The sheet of warp, being wound on the take-up and extending around the drums, is shown at a, Fig. 1. 'I is a clutch-member revoluble around element 4, 8 a fixed enlargement of element 4, and 9 a collar non-rotative but slidable on the enlargement so as by its wedge 9a to spread the dogs Ill to expand a split-ring ll into clutching relation to member I and so cause the latter and said element to rotate as one. Also revoluble around said element is a clutch-member l3 coactive to form an overrunning clutch with the surrounding flange of a drum 14 (forming a fixed part of said element) by having peripheral notches containing rollers l5 which, when member l3 rotates as per the arrow in Fig. 6, become jammed between said member and flange in a known way so that said member and element will rotate as a unit when the former assumes to rotate the faster. Clutch-members l and I3 form fixed parts of a small gear I6 and a large gear ll, respectively, and meshing with these are a large gear l8 and a small gear 19, respectively, these latter being fast on a shaft 20 forming what I term the driving element. The gearings |6l8 and ll--l9 may be respectively treated as highspeed and low-speed gearings of which the output gears l6 and Il resrectively have the clutchmembers I and I3. Shaft 20 is geared'at 2| to a Reeves variable-speed transmission 22, in turn geared to the rotor 23a of an electric motor '23 whose forward driving is determined as will appear, by a button 24 (forming a circuit-closer) normally urged to circuit-closing position by a spring 24a when a suitably guided manually operated rod 25, connected with a lever 26 engaged with collar 9, is moved from the position marked 0. When on such movement position I is reached the drive will be from element 20 through I9l| to element 4, at slow speed, forward; and when position II is reached the drive will be from element 2!] to element 4 through Iii-I6 at high speed, element 4 then rotating independently of output gear I! and its clutch-member l3.

Now as to the improvements:

It is desired to run the machine reversely at times at slow speed. Hence there are in the drum-portion 14 of element 4 thrust-pins 21 which when moved to the left (as by collar 9 when acting to free clutch-member 1) and preferably against a friction-ring 2B in clutch-member I3 cause output gear I1 and element 4.to be clutched together to rotate as a unit. (Part 9-l0-I i, taken with part 21, combine to form in effect means movable in one direction to clutch the high-speed gearing output gear, and when moved in the other direction the low-speed gearing output gear, to element 4, although in the example actual separation of part 9l0-|| from part 21 occurs when the first-named clutching is effected.) When this clutching occurs, with simultaneous de-clutching as to output gear [6, reverse driving of element 20 causes reverse driving of element 4,. It is incidentally noted that the reverse driving cannot be effected, without conflict of action or a jam, when the highspeed gearing output gear I6 is clutched to element 4 (or rod 25 in position 11) because of the clutching action that would occur between drum I4 and clutch-member l3, both then positively subject to efforts to drive them reversely though at different speeds.

The circuit connections for the motor whereby the same may be driven forwardly when rod 25 is in position I or II, or reversely when the rod is in position 0, are as follows (referring first to Fig. 11):

The motor is of the alternating-current threephase type and the leads 23 therefor (shown by heavy lines), connected to the service lines 30 in the conventional way, are controlled by what are well known in the electrical art as interlocking contactors, or circuit makers and breakers, 3|3la, assumed to be respectively moved to open or closed position by the cores 32-32a of electro-magnetic devices, as solenoids, 33-33a, said cores being connected as usual by a lever 34 which insures against either core being moved by the corresponding solenoid when the other solenoid is energized. In short, the part 3l-32-33 determine the forward driving, and the part 3la-32a33a the reverse driving of the motor. (It will be understood that the cores are mechanically connected with the contactorsas well known but not shown-so that a contactor will be in circuit-closing or opening position according, respectively, as the corresponding core is attracted or released by its solenoid.) A lead 35 extends from one service line and has branches leading to another such line, one branch, containing solenoid 33, being normally held closed by button 24 subject to spring 24a, whereas the other, containing solenoid 33a, is normally open and adapted to be closed by a manually actuated button or circuit-closer 36 normally held in open position by a spring 36a.

, When rod 25 is in 0 position the motor is dead because then both buttons are in circuit-opening position. Movement of rod 25 from position 6 starts the motor forward, as described, element 4 and all it drives moving forward at slow or high speed according as rod 25 occupies position I or position II. If, with rod 25 in 0 position (button 24a being then in open position), button 36 be made to close its circuit the motor will be driven reversely.

According to the construction so far described it will be apparent that conflict of action might ensue (notwithstanding the presence of lever 34) if shaft 20 should be driven reversely when the high-speed gearing is clutched with shaft 4 (or rod 25 in position 11) since the high-speed and low-speed gearings would then be tending to rotate shaft 4 at different speeds inasmuch as member I 4, now reversely driven, would become clutched with member l3 through the rollers l5. This is a possibility when, with rod 25 at position II, button 35 is moved to close the reverse-driving branch of the circuit, or, with the button held 'closing such branch, the rod is moved from 0 position to position II. (There would, however, be no conflict of action under'these conditions if rod 25 were in or moved to position I, because then member l3 rotated reversely, would merely idle with respect to member H.) The condition indicated is possible because the circuit may be closed through either branch by operating only a single circuit-closer.

To avoid this the circuit connections may be as in Fig. 12.

Here the arrangement is the same as in Fig. 11 excepting that lead 35a (here shown divided within its length and affording the secondary circuits) has a break in each of its solenoidcontaining divisions, the break of the division containing solenoid 32a being adapted to be closed by button 24 subject to the pressure of rod 25 when in the 0 position and the break of the division for solenoid 32 being adapted to be closed by button 24 under pressure of its spring 24a when the rod is moved from 0 position, and one or the other division being connectable with the continuing portion 35b of the lead by a switch or circuit-closer 36a connected to such portion. Here the mentioned conflict of action is not possible since the circuit can only be closed through either branch by both circuit-closers. In short, when the rod is in position I or II, the drive can be only forward, i. e., when, with 24 closing the forward-driving branch, 36a interrupts the reverse-driving and closes the forward-driving branch; if 24 is permitted to move to close the reverse-driving branch with 36a in open relation to such branch or if 36a is moved to close that branch with Me in open relation thereto the motor remains un-energized.

According to either diagram, when the controlling means (25269) is shifted to disestablish one clutching action (as at 'l) and establish the other (as at 28) and to position 0 the impulse to the motor is interrupted and a fresh impulse may be imparted thereto, as by closing circuit-closer 36-36a.

The quetch (Figs. 1 and 7) comprises, as usual, two standards 31 mounted on frame I in which are journaled the trunnions of the quetch-rolls 38, those of the lower rolls being journaled directly in the standards and those of the other two in blocks 39 movable in vertical guideways in the standards, the blocks for the upper roll having depending extensions 39a slotted to receive the trunnions of the intermediate roller so that when the former blocks are raised the rolls will be separated for admitting the warp between them. The two lower rolls are inter geared at 38a. The upper blocks have screws 40 affixed thereto and engaging nuts 4! journaled in the standards and equipped with bevel pinions 42 meshing with bevel pinions 43 on a shaft 44 journaled in the standards and having a handwheel 45, whereby, during a pass of the warp through the machine, the rolls may be made to exert some predetermined pressure thereon. It will be understood that the lowest roll dips in the size solution, contained in a tank 46 shown by dotted lines in Fig. 7.

Heretofore, having by means of the handwheel determined the right degree of pressure for the particular warp, there was no expedient by which, in case the sizing operation had to be arrested for an appreciable time (as over night), the operator could re-set the rolls so as to re-establish that degree of pressure. Hence I provide, fixed on preferably the shaft 44 by a set screw 41a, a pointer 41 and, fixed to one standard 44, a disk 48 which on its face adjoining the pointer is provided with indices numbered to indicate pounds pressure and thus form a dial. When, after stopping the machine and relieving the pressure, the machine is to be restarted the operator turns the hand-wheel until the dial returns to the pointer that numbered index which adjoined the pointer previously to relaxing the pressure.

Assume the weight of the two upper rolls is 200 lbs. The first index on the dial will be 200, to indicate that weight, and with the pressure effected by turning the hand-wheel unapplied or off the pointer should register with that index, which can be effected by manipulating the setscrew 41a and setting the pointer around the shaft. The succeeding indices may be marked 250, 300, 350, etc., to indicate theapplied pressure.

In the use of these machines it is frequently required that diiferent warps should be subjected to stretch so as to issue from the treatment with a definite increase in length; incidentally, it is required that the stretch should be constant from one end to the other of the sheet. I have heretofore proposed a belt-and-pulley transmission connecting the quetch rolls, which coact to resist the advance of the sheet, with the nearest drum, which coacts with the other drums to effect such advance. This had these faults: that there might occur, during a treatment, slippage of the belt on the pulleys and hence a variation in the stretch applied to the particular warp, and that the operator had no recourse to determine the degree of stretch being effected but by pressing his hand against the warp between the drums and quetch. In short, both the constancy and the degree of stretch were entirely uncertain quantities. According to this invention the stretch obtained is not only constant during any given treatment but adjustment is possible to the end that the stretch will be precisely that degree for which the adjustment is effected, or so that with the adjustment effected for a certain degree of stretch the result will be that every warp (of substantially the same quality) passed through the machine will emerge having exactly the degree of stretch corresponding to such adjustment.

On frame I is a housing 49 in which is journaled a shaft 50 having a pinion 5|. meshing with the gear 2a of the nearest drum, and having splined thereon a small gear 52 contained in the forked portion 53a (Fig. 10) of a shifter 53 which is fulcrumed on said shaft and has journaled therein a small gear 54 meshing with gear 52. On a shaft 55 journaled in the housing parallel with shaft 50 is fixed a system of gears 56 of graduated diameters. The shifter and its gears 52-54 may be shifted along shaft ill to bring gear 54 into mesh with any one of said gears 56, being held in the new position by any one of the notches 49a shown in the top of the housing, which in part is hinged, as at 49b. The smallest gear 56 meshes with a gear 51 in permanent mesh with a small gear 58, such gears being journaied in a carrier 59 fulcrumed on shaft 55 and having a slotted extension which may be clamped to frame I by a bolt 60. Carrier 59 may thus be shifted to engage either gear 51 or gear 58 with the gear 38a of the lowest quetch roll. In the position shown, in which said gear is so engaged, the lowest roll will be driven anti-clockwise, or in the direction for advancing the warp when it is trained around the lowest roll.
